I have no illusions about my filmmaking work but I must add I have no illusions about anybody else's either. I am very strict with myself and I think, "no, that could have been improved", "why didn't I put a little bit more then? Why didn't we come out then?" It was what I thought was right at the time and you have to stand by that. And if it completely fails you have got to say, "But that is what I meant at the time.".
